[PATCH] Enable Java on Cygwin-64

[Kai Tietz]

Hi,

I have the following comment.

boehm-gc/ChangeLog:

2014-05-11  Bernd Edlinger  <bernd.edlinger@hotmail.de>

Fix current cygwin-64 build problems.
* include/gc_config_macros.h (GC_PTHREADS): Use __CYGWIN__ instead
of __CYGWIN32__ here.
* win32_threads.c (GC_push_all_stacks): Push all X86_64 registers.
(GC_get_thread_stack_base): Get the stack base for X86_64.

That change is ok.  Please don't miss to post the changes also to boehm-gc's ML.

In general it is better to splitt patches into seprate patches.  To
put all in one isn't ease review here.

libffi/ChangeLog:

2014-05-11  Bernd Edlinger  <bernd.edlinger@hotmail.de>

Fix current cygwin-64 build problems.
* src/java_raw_api.c: Remove if !defined(FFI_NO_RAW_API).
* src/x86/ffi.c: Add if defined(__CYGWIN__).
* src/x86/win64.S (ffi_closure_win64, ffi_call_win64): Added
handling for FFI_TYPE_UINT64, FFI_TYPE_POINTER and FFI_TYPE_INT.
Added SEH information.  Fixed formatting.

Patch is ok IMO.  Nevertheless this part shall go also to libffi's ML.

libgcc/ChangeLog:

2014-05-11  Bernd Edlinger  <bernd.edlinger@hotmail.de>

* unwind-seh.c (_Unwind_Backtrace): Uncommented, finished
implementation.

This part of the patch is ok.  Please apply to trunk.

libjava/ChangeLog:

2014-05-11  Bernd Edlinger  <bernd.edlinger@hotmail.de>

Fix current cygwin-64 build problems.
* configure.host: Added handling for x86_64-*-cygwin/mingw.
* boehm.cc (_Jv_GCAttachThread, _Jv_GCDetachThread): Don't compile if
GC_WIN32_THREADS is defined.
* java/lang/natClass.cc (_Jv_InterfaceAssignableFrom): Rename interface
to source_interface.

This part of the patch looks ok too.  As here a libjava-maintainer
needs to look into too, you should post this part again to ML with
prominent marking libjava in subject line.

libjava/classpath/ChangeLog:

2014-05-11  Bernd Edlinger  <bernd.edlinger@hotmail.de>

Fix current cygwin-64 build problems.
* native/fdlibm/mprec.c (_REENT_CHECK_MP, _REENT_MP_FREELIST,
_REENT_MP_P5S, __ULong, __Long): Undefine previous definitions.

Same here.  Looks ok to me, too.  Nevertheless please post it as
separate thread to ML.

Thanks,
Kai
